'The Big Bang Theory' cast takes sweet group selfies to celebrate season 10 amid reports this season could be the show's last

CBS Boss is 'Confident' 'Big Bang Theory' Won't End After Upcoming 10th Season

It all started with a big selfie! The Big Bang Theory cast is back on their Los Angeles set to film Season 10 of the hit CBS comedy. But it wouldn't be the proper start of a season without a giant cast shot.

Thankfully, star Kaley Cuoco pulled out her selfie stick to take a pic with her co-stars Johnny Galecki, Jim Parsons, Mayim Bialik, Melissa Rauch, and Kunal Nayyar.

The actress' ex and co-star, Galecki, got in on the action, posting another polaroid shot that caught Cuoco snapping the cast photo with her selfie stick.

There have been rumors that the 10th season could be the last for the Big Bang Theory, as the main stars have only signed contracts through the end of this season. However, CBS does not seem to think this will be the end of the show.

"We are very confident that everyone wants Big Bang past year 10 and I know Warner Bros. will make those deals," CBS President Glenn Geller said at the TCAs earlier this month.

But showrunner Steve Molaro seemed to feel differently, recently telling the Hollywood Reporter, "The reality is that maybe season 10 is the ending point."
